Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533492, here are decompositions:

31 + 31533461 = 31533492
41 + 31533451 = 31533492
43 + 31533449 = 31533492
61 + 31533431 = 31533492
79 + 31533413 = 31533492
83 + 31533409 = 31533492
103 + 31533389 = 31533492
113 + 31533379 = 31533492

Showing the first eight; more decompositions exist.
